Title: Limitations in sequestering carbon in forests
1Limitations in sequestering carbon in forests
- By
- Promode Kant
- Indian Forest Service
2Annual addition to atmospheric carbon-di-oxide
- Atmosphere gives 2 Gt C to surface ocean and 3 Gt
C to terrestrial ecosystems annually thru
photosynthesis - Atmosphere receives 1.5-2 Gt C from deforestation
- Atmosphere receives 6.5 Gt C from fossil fuel use
and cement production
3The possibilities in forestry
- NEP Net Ecosystem Production is the net
accumulation of organic matter by an ecosystem,
NEP Net Primary Production heterotrophic
respiration (losses caused by herbivory and by
decomposition of debris in soil biota). Global
Estimation at 10 GtC/yr - Net Biome Production (NBP) is the net production
of organic matter in a region containing many
ecosystems and includes other anthropogenic and
natural causes of respiration also like
harvesting, fires forest clearances, etc. Global
estimate at 10 of NEP.
4THE REALITY only 1 approved CDM project yet in
forestry sector
5Afforestation/Reforestation projects under CDM
- 20 project methodologies proposed
- 11 rejected or withdrawn
- Changes suggested in 4
- 2 under examination
- Only 1 approved in China 33K tCO2/year
6Why?
- Difficulties in establishing additionality
- Difficulties in assessing leakages
- Difficulties in baseline assessment
- Conflict with biodiversity conservation
7Why?
- Issue of non-permanence of carbon sequestered
temporary CERs heavy discount on tCERs - Leading to low economic viability of the projects
- Carbon credits not enhancing economic returns
over simple plantation projects also makes
additionality difficult to establish
8Does the recent approval in China signify
progress?
- 4000 ha AR project in two sites, deforested since
1950, in Pearl River Basin in southern China 33
K CO2 per annum, 30 yrs crediting period, about
1M t CO2 total - Existing vegetation has remained degraded with
lt20 crown density over last many years - Reforestation with 5 species including eucalyptus
to enhance productivity - Leakages on account of removal by people has been
considered negligible - Leakages considered only on account of N2O
emission thru fertilizer use and in
transportation of harvested timber by using
fossil fuel much easier to assess
9Does the recent approval in China signify
progress?
- Return on investment without CER 8.4 and with
CER 15.7 - Norm in China for agricultural investment is 12,
hence it was presumed that without CERs this
project would not have been taken up. Hence
additional - Large gap between required investment and
availability of funding among local communities
and low chances of obtaining loans from
commercial banks taken as barrier to investments.
Hence additional as financial barriers would have
prevented the project otherwise
10The replicability of Chinese methodology
- Without project local farmers would have had no
access to quality planting material. Hence
additional - Also there were no existing skills in forest
management which are now being brought in. Hence
additional - Additionality tests appear to have become
reasonable, hence it should help other projects
in future - But leakage assumptions may not hold for other
tropical countries like India with large
dependency on forests by local people - Also biodiversity conservation requirements may
not hold in more warmer and humid conditions as
the species mix would be far more complex
11The replicability of Chinese methodology
- Land opportunity costs are usually prohibitive
unlike the Chinese case where lands were
considered unattractive for other uses - Transaction costs for monitoring, measurements
etc elsewhere may be prohibitively high unlike in
Chinese case, with the central govt being a
participant, where the resources of the Chinese
Academy of Forestry are being utilized at
operational costs alone - Reforestation projects may continue to encounter
difficulties
12Is agro-forestry a better option?
- Yes, easier to assess and manage leakages in
private holdings, lower transaction costs,
sharing of costs with agricultural operations,
lowered costs of ensuring biodiversity
conservation and sustainable development, no
difficulty of obtaining stakeholders consent - But definition chosen by most countries for
forests may pose biggest problem
13National Forest definitions National Forest definitions National Forest definitions National Forest definitions
 Minimum crown cover 10-30 Minimum area 0,05 ha - 1ha Minimum height 2- 5 m
China 20 0.067 2
Costa Rica 30 1.000 5
Congo 30 1.000 5
Honduras 30 1.000 5
India 30 0.050 5
Nicaragua 20 1.000 4
Uganda 30 1.000 5
Vietnam 30 0.500 3
Yemen 30 0.500 3
14Is agro-forestry a better option?
- Except for China Nicaragua these definitions
favour reforestation of degraded areas as all
degraded lands lt30 crown cover eligible for
reforestation under CDM - But unfavorable to agriforests as farmers would
be required to create a crown cover of minimum
30 density to claim C credits excessive shade
- not possible with most agricultural crops - small minimum land area requirement is not of
help as it enhances transaction costs
15The real options in forestry
- Heavy discounts on temporary CERs, high
transaction monitoring costs, higher risks
limit AR - Forests as source of renewable energy for
replacing fossil fuel, both wood and seeds,
leading to permanent CERs, easier to cross
additionality tests and leakage assessments, show
much greater promise
